My display tank ph crept up to 8.9 during the middle of the day so I started dosing 8 - 12 ml of vinegar daily (65 gal tank) to get the ph down. So far so good and I have not done any water changes in 3 to 4 months. I don't plan to increase the vinegar dosage.

I did finally buy some reef crystals so I'll do a 5 gal change this weekend until I get back to 15 gallon changes.

I think you are referring to KH, not PH.
